To all whom it may concern: any other suitable devices, this feature of the Beitknown that we,CHARLEs H.WELLMAN, machine forming no part of our present ingo ALFRED ERNST, and FREDELLFA H. MOYER, vention. The hopper-bottom hasa forwardlycitizens of the United States, and residents of extending portion 3, to which is pivoted the 5 Cleveland, Ohio, have invented certain Imlower end of the pusher-plate 4 and also one provementsin aCombined Charging and Dis or more bars 5, which by preference carry a charging Device for Coke-Ovens, of whichthe plate 6 of the full 'width of the hopper. In 55 following is a specification. the present instance a pair of these bars is Our invention consists of an improvement shown; but there may be more than two, if

When the hopper tionassumed when thehopperisbeingcharged has received its load of coal, the position of with coal.

When the pusher-plate and its brace-bars are moved to horizontal position, the bracebars overlap the pusher-plate to some extent, and the parts are mutually recessed, as shown at 9 and 10, to permit such overlap.

In Fig. '7 the pusher t is shown in the horizontal position in line with the projecting portion 3 of the bottom plate of the hopper and the hopper-closing plate 6 and bracebars 5 are shown in the elevated position. In practice the parts never assume this speeific relation to each other; but this disposal of them has been adopted in order to best illustrate the notches 7 and recesses 9 and 10.

Having thus described 'our invention, we claim and desire to secure by Letters Patexit 1. The combination of the movable hopperbottom of a coke-oven-charging m aohine,witl1 a pusher-plate and one or more brace-bars therefor, both the plate and its brace bar or bars being pivotally mounted upon the forward end of said hopper-bottom whereby they can be swung into horizontal position for withdrawal beneath the charge of coal in the oven, substantially as specified.

2. The combination of the movable hopperbottom of a coke-oven-charging machine,with a pusher-plate and one or more brace-bars therefor, both the plate and the brace bar or bars being pivotally mounted upon the forward end of the hopper-bottom, said brace bar or bars having a plate for closing the forward end of the hopper, and the pivotal mounting of the pusher and brace being such that they can both be thrown down into horirarest zontal position for withdrawal beneath the coal in the oven, substantially as specified.

3. The combination of the movable hopperbottom of a coke-oven-charging machine,with a pusher-plate and one or more brace-bars therefor, both the plate and the brace bar or bars being pivotally mounted upon the forward end of the hopper-bottom, said brace bar or bars having a plate for closing the forward end of the hopper, and the pivotal mounting of the pusher and brace being such that they can both be thrown down into horizontal position for withdrawal beneath the coal in the oven, and the pusher can also serve as a brace for the plate which closes the end of the hopper, substantially as specified.

4. The combination of the movable hopperbottorn ofa coke-oven-charging maohine,with a pusher-plate and one or more brace-bars therefor, both the plate and its brace bar or bars being pivotally mounted upon the forward end of said hopper-bottom whereby they can be swung into horizontal position for withdrawal beneath the charge of coal in the oven, the brace bar or bars overlapping the pusher-plate and the parts being mutually recessed in these overlapping portions, substantially as specified.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
